I am not sure if this is right , but when i was trying to do numerical methods this definition was a bit helpful .

Quote:
 for example , for a polynomial ... a solution of a polynomial equation is also called a root of the polynomial ... a value for the variable that makes the polynomial zero if you can't find an exact expression, then you can use numerical methods to get approximations ... with numerical methods you can choose how close to zero you want, and it will give you a value that's at least that close ...
Also , there is a good quality text book freely available for download on numerical methods .
